Liquid Crystal Shutter Driver

General Description

The Supertex HV508 is a 45V liquid crystal shutter driver in

an 8-Lead SOIC surface mount package. It consists of two

outputs that provide square waves of opposite phase. The

liquid crystal shutter is connected between the two outputs.

Its equivalent load can be approximated as a resistor in

parallel with a capacitor. Minimum resistance is 1.0MΩ and

maximum capacitance is 0.1µF.

The HV508 has three input supply voltages, HV

IN, LVIN, and

V

DD. The output’s amplitude will be either LVIN or HVIN. A logic

high on the HV

EN input will set the output to operate from the

HV

IN supply. A logic low on the HVEN input will set the output

to operate from the LV

IN supply. The output frequency is set

by the logic input frequency applied on the POL input.
